As with most things, it depends. Do you have good auto repair/mechanic type experience?
Mark Basch came out to Virginia and installed his old supercharger on my car this past week. I helped where possible, and think I have learned a bit about the install. Mark installed larger injectors, fuel regulator, fuel pump voltage boost circuit, and supercharger. I think Mark could have finished faster without all my questions, but I wanted to learn as much as possible about my car.
The vacuum hose manifold is modified and the hoses are connected in a different sequence. Some of the nuts on the supercharger are difficult to get at without a “C” shaped handle 14 mm box wrench, but most things are pretty standard stuff. The most difficult thing is in knowing which items are taken off and installed in which order. There are also the intangible things, such as how to properly tension the drive belt. I would not consider this a beginners project. If you are good and have good instructions, I believe you could do this at home. It would also be handy to have a “lifeline” to call if you have questions.
Good luck on what ever you choose. You will be pleased with the additional performance.
